CROSS REFERENCE TO RELATED APPLICATION

This application claims priority to U.S. Provisional Application No. 62/675,408, filed May 23, 2018, which is hereby incorporated by reference in its entirety.

FIELD OF THE DISCLOSURE

The disclosure relates to the field of plant breeding and, more specifically, to the tomato variety NUN 09220 TOF. The disclosure further relates to vegetative reproductions of NUN 09220 TOF, methods for tissue culture of NUN 09220 TOF, methods for regenerating a plant from such a tissue culture, and to phenotypic variants of NUN 09220 TOF.

BACKGROUND

The goal of plant breeding is to combine various desirable traits in a single variety. Such desirable traits may include greater yield, resistance to diseases, insects or other pests, tolerance to heat and drought, better agronomic quality, higher nutritional value, enhanced growth rate and improved fruit properties.

Breeding techniques take advantage of a plant's method of pollination. There are two general methods of pollination: a plant self-pollinates if pollen from one flower is transferred to the same or another flower of the same genotype. A plant cross-pollinates if pollen comes to it from a flower of a different genotype.

Plants that have been self-pollinated and selected for (uniform) type over many generations become homozygous at almost all gene loci and produce a uniform population of true breeding progeny of homozygous plants. A cross between two such homozygous plants of different lines produces a uniform population of hybrid plants that are heterozygous for many gene loci. The extent of heterozygosity in the hybrid is a function of the genetic distance between the parents. Conversely, a cross of two plants each heterozygous at a number of loci produces a segregating population of hybrid plants that differ genetically and are not uniform. The resulting non-uniformity makes performance unpredictable.

The development of uniform varieties requires the development of homozygous inbred plants, the crossing of these inbred plants to make hybrids, and the evaluation of the hybrids resulting from the crosses. Pedigree breeding and recurrent selection are examples of breeding methods that have been used to develop inbred plants from breeding populations. Those breeding methods combine the genetic backgrounds from two or more plants or various other broad-based sources into breeding pools from which new lines are developed by selfing and selection of desired phenotypes. The new plants are evaluated to determine which have commercial potential.

Tomato (Solanum lycopersicum and closely related species) is naturally a diploid and the basic chromosome number of the genus is x=12, most are 2n=2x=24, including the cultivated ones. It originated in the New World and has since become a major food crop.

Tomato cultivars may be grouped by maturity, i.e. the time required from planting the seed to the stage where fruit harvest can occur. Standard maturity classifications include ‘early’, ‘midseason’ or ‘late-maturing’. Another classification for tomatoes is the developmental timing of fruit set. ‘Determinate’ plants grow foliage, then transition into a reproductive phase of flower setting, pollination and fruit development. Consequently, determinant cultivars have a large proportion of the fruit ripen within a short time frame. Growers that harvest only once in a season favor determinant type cultivars. In contrast, ‘indeterminate’ types grow foliage, then enter a long phase where flower and fruit development proceed along with new foliar growth. Growers that harvest the same plants multiple times favor indeterminate type cultivars.

Tomatoes can also be classified by their target markets: fresh market and processing tomatoes. Fresh-market tomatoes are primarily used for salads, salad bar and sandwiches, and require good storage properties. On the other hand, processing tomatoes generally requires red colored and pink to red/crimson fruit flesh and higher percentage of soluble solids. Processing tomatoes can be canned whole, canned, diced or chopped, dried, roasted, pasted, puréed or concentrated, juiced, frozen, or put into ready-made dishes, for example, sauces, stews or soups.

In 2017, World Atlas reported that the worldwide production of tomatoes amounted to 170.8 million tons. United States is ranked as the third largest producer of tomatoes in the world, next to China and India. Tomatoes are available in the United States year-round, with California and Florida being the major producers. Fresh-market tomatoes are available from May to December although supply peaks in July and in September through October. Processing tomatoes have the greatest supply from August to September.

In response to more recent consumer demands for dietary diversity, tomato breeders have developed a wider range of colors. In addition to expanding the range of red colored fruits, there are cultivars that produce fruits that are creamy white, lime green, yellow, green, golden, orange and purple. Additionally, there are multi-colored varieties exemplified by mainly red fruited varieties with green shoulders, and both striped- and variegated-colored fruit.

Likewise, “UPOV methods” to determine specific parameters for the characterization of tomato are described at upov.int.

“RHS” refers to the Royal Horticultural Society of England which publishes an official botanical color chart quantitatively identifying colors according to a defined numbering system. The chart may be purchased from Royal Horticulture Society Enterprise Ltd RHS Garden; Wisley, Woking; Surrey GU236QB, UK, e.g., the RHS color chart: 2007.

“Reference Variety for NUN 09220 TOF” refers herein to variety Mountain Magic from Johnny's Selected Seeds, which has been planted in a trial together with NUN 09220 TOF. USDA descriptors of NUN 09220 TOF were compared to the USDA descriptors of NUN 09013 TOF.

“Plant part” includes any part of a plant, such as a plant organ (e.g., harvested or non-harvested fruits), a plant cell, a plant protoplast, a plant cell tissue culture or a tissue culture from which a whole plant can be regenerated, a plant cell that is intact in a plant, a clone, a micropropagation, plant callus, a plant cell clump, a plant transplant, a vegetative propagation, a seedling, a fruit, a harvested fruit, a part of a fruit, a leaf, a part of a leaf, pollen, an ovule, an embryo, a petiole, a shoot or a part thereof, a stem or a part thereof, a root or a part thereof, a root tip, a cutting, a seed, a part of a seed, hypocotyl, cotyledon, a scion, a graft, a stock, a rootstock, a pistil, an anther, and a flower or parts of any of these and the like.

Alternatively, a plant part may also include a plant seed which comprises one or two sets of chromosomes derived from the parent plant, e.g., from NUN 09220 TOF. An F2 progeny produced from self-pollination of NUN 09220 TOF will thus comprise two sets of chromosomes derived from NUN 09220 TOF, while an F2 progeny derived from cross-fertilization of NUN 09220 TOF will comprise only one set of chromosomes from NUN 09220 TOF, and the other set of chromosomes from the other parent.

“Harvest maturity” is referred to as the stage at which a tomato fruit is ripe or ready for harvest or the optimal time to harvest the fruit for the market, for processing or for consumption. In one aspect, harvest maturity is the stage which allows proper completion of the normal ripening.

“Harvested plant material” refers herein to plant parts (e.g., single fruits or clusters of fruits detached from the whole plant), which have been collected for further storage and/or further use.

“Yield” means the total weight of all tomato fruits harvested per hectare of a particular line or variety. It is understood that “yield” expressed as weight of all tomato fruits harvested per hectare can be obtained by multiplying the number of plants per hectare times the “yield per plant”.

“Marketable yield” means the total weight of all marketable tomato fruits, especially fruit which is not cracked, damaged or diseased, harvested per hectare of a particular line or variety. A “marketable fruit” is a fruit that has commercial value.

“Rootstock” or “stock” refers to the plant selected for its roots, in particular for the resistance of the roots to diseases or stress (e.g., heat, cold, salinity etc.). Normally the quality of the fruit of the plant providing the rootstock is less important.

“Scion” refers to a part of the plant attached to the rootstock. This plant is selected for its stems, leaves, flowers, or fruits. The scion contains the desired genes to be duplicated in future production by the stock/scion plant and may produce the desired tomato fruit.

“Stock/scion” or grafted plant refers to a tomato plant comprising a rootstock from one plant grafted to a scion from another plant.

A plant having “all the physiological and morphological characteristics” of a referred-to-plant means a plant showing the physiological and morphological characteristics of the referred-to-plant when grown under the same environmental conditions, preferably in the same experiment; the referred-to-plant can be a plant from which it was derived, e.g., the progenitor plant, the parent, the recurrent parent, the plant used for tissue- or cell culture, etc. A physiological or morphological characteristic can be a numerical characteristic or a non-numerical characteristic. In one aspect, a plant has “all but one, two or three of the physiological and morphological characteristics” of a referred-to-plant, or “all the physiological and morphological characteristics” of Table 1 and/or 2 and/or 3 or “all or all but one, two or three of the physiological and morphological characteristics” of Table 1 and/or 2 and/or 3.

The physiological and/or morphological characteristics mentioned above are commonly evaluated at significance levels of 1%, 5% or 10% if they are numerical (quantitative), or for having an identical degree (or type) if not numerical (not quantitative), if measured under the same environmental conditions. For example, a progeny plant or a Single Locus Converted plant or a mutated plant of NUN 09220 TOF may have one or more (or all) of the essential physiological and/or morphological characteristics of said variety listed in Table 1 and/or 2 and/or 3, as determined at the 5% significance level (i.e., p<0.05), when grown under the same environmental conditions.

“Distinguishing characteristics” or “distinguishing morphological and/or physiological characteristics” refers herein to the characteristics which distinguish (i.e., are different) between the new variety and other tomato varieties, such as the Reference Variety, when grown under the same environmental conditions. The distinguishing characteristics between NUN 09220 TOF and Reference Variety are described herein and also can be seen in Table 1 and/or Table 2. When comparing NUN 09220 TOF with different varieties, the distinguishing characteristics will be different. In one aspect, the distinguishing characteristics may therefore include at least one, two, three or more (or all) of the characteristics listed in Table 1 and/or 2 and/or 3. All numerical distinguishing characteristics are statistically significantly different at p<0.05 between NUN 09220 TOF, and the other variety, e.g., Reference Variety.

NUN 09220 TOF has the following distinguishing characteristics when compared to the Reference Variety, NUN 09013 TOF: 1) an average number of nodes before 1^(st) inflorescence; 2) an average length of internode after 1^(st) inflorescence; 3) an average length of internode after 2^(nd) inflorescence; 4) an average plant height of mature plant; 5) average length of mature fruit (stem axis); 6) an average length of pedicel (from joint to calyx attachment); 7) an average number of locules; 8) an average thickness of pericarp; 9) an average diameter of stem scar; and 10) color of mature fruit. This can be seen in Table 1 and/or 2, where the USDA characteristics of NUN 09220 TOF are compared to the characteristics of Reference Variety, when grown under the same environmental conditions.

Thus, a tomato plant “comprising the distinguishing characteristics of NUN 09220 TOF” (such as a progeny plant) refers herein to a plant which does not differ significantly from said variety in the distinguishing characteristics above. Therefore, in one aspect a plant (such as a progeny plant of NUN 09220 TOF) is provided which does not differ significantly from NUN 09220 TOF in the distinguishing characteristics above.

Similarity and differences between two different plant lines or varieties can be determined by comparing the number of morphological and/or physiological characteristics (e.g., the characteristics as listed in Table 1 and/or 2 and/or 3) that are the same (i.e., statistically not significantly different) or that are different (i.e., statistically significantly different) between the two plant lines or varieties when grown under the same environmental conditions. A numerical characteristic is considered to be “the same” when the value for a numeric characteristic is not significantly different at the 1% (p<0.01) or 5% (p<0.05) significance level, using one way analysis of variance (ANOVA), a standard method known to the skilled person. Non-numerical or “degree” or “type” characteristic is considered “the same” when the values have the same “degree” or “type” when scored using USDA and/or UPOV descriptors, if the plants are grown under the same environmental conditions.

A “plant line” is, for example, a breeding line which can be used to develop one or more varieties. A breeding line is typically highly homozygous.

“Hybrid variety” or “F1 hybrid” refers to the seeds harvested from crossing two inbred (nearly homozygous) parental lines. For example, the female parent is pollinated with pollen of the male parent to produce hybrid (F1) seeds on the female parent.

“Regeneration” refers to the development of a plant from cell culture or tissue culture or vegetative propagation.

“Vegetative propagation”, “vegetative reproduction” or “clonal propagation” are used interchangeably herein and mean a method of taking a part of a plant and allowing that plant part to form at least roots, and also refer to the plant or plantlet obtained by that method. Optionally, the vegetative propagation is grown into a mature plant. The skilled person is aware of what plant parts are suitable for use in the method.

“Selfing” refers to self-pollination of a plant, i.e., the transfer of pollen from the anther to the stigma of the same plant.

“Crossing” refers to the mating of two parent plants. The term encompasses “cross-pollination” and “selfing”.

“Cross-pollination” refers to the fertilization by the union of two gametes from different plants.

As used herein, the terms “resistance” and “tolerance” are used interchangeably to describe plants that show no symptoms or significantly reduced symptoms to a specified biotic pest, pathogen, abiotic influence or environmental condition compared to a susceptible plant. These terms are optionally also used to describe plants showing some symptoms but that are still able to produce marketable product with an acceptable yield.

The term “traditional breeding techniques” encompasses herein crossing, selfing, selection, doubled haploid production, embryo rescue, protoplast fusion, marker assisted selection, mutation breeding, etc. as known to the breeder (e.g., methods other than genetic modification/transformation/transgenic methods), by which, for example, a genetically heritable trait can be transferred from one tomato line or variety to another.

“Backcrossing” is a traditional breeding technique used to introduce a trait into a plant line or variety. The plant containing the trait is called the donor plant and the plant into which the trait is transferred is called the recurrent parent. An initial cross is made between the donor parent and the recurrent parent to produce a progeny plant. Progeny plants which have the trait are then crossed to the recurrent parent. After several generations of backcrossing and/or selfing the recurrent parent comprises the trait of the donor. The plant generated in this way may be referred to as a “single trait converted plant”. The technique can also be used on a parental line of a hybrid.

“Progeny” as used herein refers to a plant obtained from a plant designated NUN 09220 TOF. A progeny may be obtained by regeneration of cell culture or tissue culture or parts of a plant of said variety or selfing of a plant of said variety or by producing seeds of a plant of said variety. In further aspects, progeny may also encompass plants obtained from crossing of at least one plant of said variety with another tomato plant of the same variety or another variety or (breeding) line, or with wild tomato plants. A progeny may comprise a mutation or a transgene. A “first generation progeny” or is the progeny directly derived from, obtained from, obtainable from or derivable from the parent plant by, e.g., traditional breeding methods (selfing and/or cross-pollinating) or regeneration (optionally combined with transformation and mutation). Thus, a plant NUN 09220 TOF is the male parent, the female parent or both of a first generation progeny of that variety. Progeny may have all the physiological and morphological characteristics of variety NUN 09220 TOF when grown under the same environmental conditions. Using common breeding methods such as backcrossing or recurrent selection, mutation or transformation, one or more specific characteristics may be introduced into said variety, to provide a plant comprising all but 1, 2, or 3 or more of the morphological and physiological characteristics of NUN 09220 TOF (as listed in Table 1 and/or 2 and/or 3).

The terms “gene converted” or “conversion plant” or “single locus converted plant” in this context refer to tomato plants which are developed by traditional breeding techniques e.g., backcrossing, or via genetic engineering or through mutation breeding, wherein essentially all of the desired morphological and physiological characteristics of the parent variety or line are recovered, in addition to the one or more genes transferred into the parent via e.g., backcrossing technique (optionally including reverse breeding or reverse synthesis of breeding lines). It is understood that only the addition of a further characteristic (e.g., addition of gene conferring a further characteristic, such as a disease resistance gene), but also the replacement/modification of an existing characteristic by a different characteristic is encompassed herein.

Likewise, a “Single Locus Converted (Conversion) Plant” refers to plants developed by plant breeding techniques comprising or consisting of mutation and/or by genetic transformation and/or by traditional breeding techniques, such as backcrossing, wherein essentially all of the desired morphological and physiological characteristics of a tomato variety are recovered in addition to the characteristics of the single locus having been transferred into the variety via the backcrossing technique. In case of a hybrid, the gene may be introduced in the male or female parental line.

“Average” refers herein to the arithmetic mean.

The term “mean” refers to the arithmetic mean of several measurements. The skilled person understands that the appearance of a plant depends to some extent on the growing conditions of said plant. Thus, the skilled person will know typical growing conditions for NUN 09220 TOF. The mean, if not indicated otherwise within this application, refers to the arithmetic mean of measurements on at least 10 different, randomly selected plants of a variety or line.

Optionally, the plant has one, two or three of the physiological and morphological characteristics that are affected by a mutation or by transformation. In another aspect, the disclosure provides a tomato plant regenerated from the tissue or cell culture of NUN 09220 TOF, wherein the plant has all of the physiological and morphological characteristics of said variety determined at the 5% significance level when grown under the same environmental conditions. In these cases, similarity or difference of a characteristic is determined by measuring the characteristics of a representative number of plants grown under the same environmental conditions, determining whether type/degree characteristics are the same and determining whether numerical characteristics are different at the 5% significance level.

NUN 09220 TOF, or its progeny, or a plant having all physiological and/or morphological characteristics but one, two or three which are different from those of NUN 09220 TOF, can also be reproduced using vegetative reproduction methods. Therefore, the disclosure provides for a method of producing a plant, or plant part of NUN 09220 TOF, comprising vegetative propagation of NUN 09220 TOF. Vegetative propagation comprises regenerating a whole plant from a plant part of variety NUN 09220 TOF, from a progeny or from or a plant having all physiological and/or morphological characteristics of said variety but one, two or three different characteristics, such as a cutting, a cell culture or a tissue culture.

The disclosure also provides methods of vegetatively propagating a part of the plant of the disclosure NUN 09220 TOF. In certain aspects, the method comprises: (a) collecting tissue or cells capable of being propagated from NUN 09220 TOF; (b) cultivating said tissue or cells to obtain proliferated shoots; and (c) rooting said proliferated shoots, to obtain rooted plantlets. Steps (b) and (c) may also be reversed, i.e., first cultivating said tissue to obtain roots and then cultivating the tissue to obtain shoots, thereby obtaining rooted plantlets. The rooted plantlets may then be further grown, to obtain plants. In one embodiment, the method further comprises step (d) growing plants from said rooted plantlets. Therefore, the method also comprises regenerating a whole plant from said part of NUN 09220 TOF. In a particular aspect, the part of the plant to be propagated is is a cutting, a cell culture or a tissue culture.

Preferably, the fruit is collected at harvest maturity. In another embodiment, the fruit is collected when the seed is ripe. A plant of NUN 09220 TOF can be produced by seeding directly in the soil (e.g., field) or by germinating the seeds in controlled environment conditions (e.g., greenhouses, hydroponic cultures, etc.) and optionally then transplanting the seedlings into the field. For example, the seed can be sown into prepared seed beds where they will remain for the entire production the crop (see, e.g., https://anrcatalog.ucanr.edu/pdf/7228.pdf). Tomatoes can be grown with a support system such as poles (i.e., stakes) to keep the fruit from touching the ground or as bushes without support. Alternatively, plastic row covers can also be used to control the temperature. Mulches or plastic tunnels can also be used to protect the plant from frost (see, e.g., https://anrcatalog.ucanr.edu/pdf/8017.pdf). Tomato can also be grown entirely in greenhouses. Moreover, said variety can be grown in hydroponic cultures as described herein in, e.g., US2008/0222949, which is herein incorporated by reference in its entirety, and the skilled person is familiar with various type of hydroponic cultures.

In still another aspect, the disclosure provides a method of producing a tomato plant, comprising crossing a plant of tomato NUN 09220 TOF with a second tomato plant at least once, allowing seed to develop and optionally harvesting said progeny seed. The skilled person can select progeny from said crossing. Optionally, the progeny (grown from the progeny seed) is crossed twice, thrice, or four, five, six or seven times, and allowed to set seed. In one aspect, the first “crossing” further comprises planting seeds of a first and a second parent tomato plant, often in proximity so that pollination will occur; for example, mediated by insect vectors. Alternatively, pollen can be transferred manually. Where the plant is self-pollinated, pollination may occur without the need for direct human intervention other than plant cultivation. After pollination the plant can produce seed.

In yet another aspect, the disclosure provides a method of producing a tomato plant, comprising selfing a plant of variety NUN 09220 TOF one or more times, and selecting a progeny plant from said selfing. In one aspect, the progeny plant retains all the distinguishing characteristics of NUN 09220 TOF described above when grown under the same environmental conditions. In a different aspect, the progeny plant comprises all (or all but one, two or three) of the physiological and morphological characteristic of NUN 09220 TOF of Table 1 and/or 2 and/or 3.

In other aspects, the disclosure provides a progeny plant of variety NUN 09220 TOF such as a progeny plant obtained by further breeding of NUN 09220 TOF. Further breeding with NUN 09220 TOF includes selfing that variety one or more times and/or cross-pollinating NUN 09220 TOF with another tomato plant or variety one or more times. In particular, the disclosure provides for a progeny plant that retains all the essential morphological and physiological characteristics of NUN 09220 TOF or, in another aspect, a progeny plant that retains all, or all but one, two or three, of the morphological and physiological characteristics of NUN 09220 TOF, optionally all or all but one, two or three of the characteristics as listed in Table 1 and/or 2 and/or 3, when grown under the same environmental conditions, determined at the 5% significance level for numerical characteristics. In a particular aspect, the progeny is a first generation progeny, i.e., the ovule or the pollen (or both) used in the crossing is an ovule or pollen of variety NUN 09220 TOF, where the pollen comes from an anther and the ovule comes from an ovary of NUN 09220 TOF. In another aspect, the disclosure provides for a vegetative reproduction of the variety and a plant having all, or all but 1, 2, or 3 of the physiological and morphological characteristics of NUN 09220 TOF (e.g., as listed in Table 1 and/or 2 and/or 3).

The disclosure also provides a method for collecting pollen of NUN 09220 TOF, comprising collecting pollen from a plant of NUN 09220 TOF. Alternatively, the method comprises growing a plant of NUN 09220 TOF until at least one flower contains pollen and collecting the pollen. In particular aspect, the pollen is collected when it is mature or ripe. A suitable method for collecting pollen comprises collecting anthers or the part of the anther that contains pollen, for example, by cutting the anther or the part of the anther off. Pollen can be collected in a container. Optionally, collected pollen can be used to pollinate a tomato flower.

The morphological and/or physiological differences between two different individual plants described herein (e.g., between NUN 09220 TOF and a progeny of NUN 09220 TOF) or between a plant of NUN 09220 TOF or progeny of said variety, or a plant having all, or all but 1, 2, or 3, of the physiological and morphological characteristics of NUN 09220 TOF, (or all, or all but 1, 2, or 3 of the characteristics as listed in Table 1 and/or 2 and/or 3) and another known variety can easily be established by growing said variety next to each other or next to the other variety (in the same field, under the same environmental conditions), preferably in several locations which are suitable for said tomato cultivation, and measuring morphological and/or physiological characteristics of a number of plants (e.g., to calculate an average value and to determine the variation range/uniformity within the variety). For example, trials can be carried out in Acampo Calif., USA (N 38 degrees 07′261″/W 121 degrees 18′ 807″, USA), whereby various characteristics, for example maturity, days from seeding to harvest, plant habit, plant attitude, stem branching, leaf color, inflorescence, shape of calyx, fruit shape, number of locules, fruit pattern, fruit color, flesh color, fruit size, disease resistance, insect resistance, can be measured and directly compared for species of tomato. Thus, the disclosure comprises tomato plant having one, two or three physiological and/or morphological characteristics which are different from those of the plant of NUN 09220 TOF and which otherwise has all the physiological and morphological characteristics of the plant of NUN 09220 TOF, when determined at the 5% significance level for plants grown under the same environmental conditions. In another aspect, the different characteristic(s) is/are result of breeding with NUN 09220 TOF and selection of progeny plant comprising 1, 2 or 3 characteristics which are different than in NUN 09220 TOF. In another aspect, the different characteristic is the result of a mutation (e.g., spontaneous mutation or a human induced mutation through e.g., targeted mutagenesis or traditional mutagenesis such as chemically or radiation induced mutagenesis), or it is the result of transformation.

The morphological and physiological characteristics (and the distinguishing characteristics) of NUN 09220 TOF are provided in the Examples, in Table 1 and/or 2 and/or 3. Encompassed herein is also a plant obtainable from NUN 09220 TOF (e.g., by selfing and/or crossing and/or backcrossing with said variety and/or progeny of said variety) comprising all or all but one, two or three of the physiological and morphological characteristics of NUN 09220 TOF listed in Table 1 and/or 2 and/or 3 as determined at the 5% significance level for numerical characteristics or identical for non-numerical characteristics when grown under the same environmental conditions and/or comprising one or more (or all; or all except one, two or three) characteristics when grown under the same environmental conditions. The morphological and/or physiological characteristics may vary somewhat with variation in the environment (such as temperature, light intensity, day length, humidity, soil, fertilizer use), which is why a comparison under the same environmental conditions is preferred. Colors can best be measured using the Royal Horticultural Society (RHS) Chart.

In yet a further aspect, the disclosure provides for a method of producing a new tomato plant. The method comprises crossing NUN 09220 TOF, or a plant comprising all but 1, 2, or 3 of the morphological and physiological characteristics of NUN 09220 TOF (as listed in Table 1 and/or 2 and/or 3), or a progeny plant thereof, either as male or as female parent, with a second tomato plant (or a wild relative of tomato) one or more times, and/or selfing a tomato plant of NUN 09220 TOF, or a progeny plant thereof, one or more times, and selecting progeny from said crossing and/or selfing. The second tomato plant may, for example, be a line or variety of the species Solanum Lycopersicon, S. chilense, S. habrochaites, S. penelli, S. peruvianum, S. pimpinellifolium or other Solanum species.

The disclosure provides for methods of producing plants which retain all the morphological and physiological characteristics of a plant described herein. The disclosure also provides for methods of producing a plant comprising all but 1, 2, or 3 or more of the morphological and physiological characteristics of NUN 09220 TOF (e.g., as listed in Table 1 and/or 2 and/or 3), but which are still genetically closely related to said variety. The relatedness can, for example be determined by fingerprinting techniques (e.g., making use of isozyme markers and/or molecular markers such as Single-nucleotide polymorphism (SNP) markers, amplified fragment length polymorphism (AFLP) markers, microsatellites, minisatellites, Random Amplified Polymorphic DNA (RAPD) markers, restriction fragment length polymorphism (RFLP) markers and others). A plant is “closely related” to NUN 09220 TOF if its DNA fingerprint is at least 80%, 90%, 95% or 98% identical to the fingerprint of that variety. In a particular aspect AFLP markers are used for DNA fingerprinting (see, e.g., Vos et al. 1995, Nucleic Acid Research 23: 4407-4414). A closely related plant may have a Jaccard's Similarity index of at least about 0.8, preferably at least about 0.9, 0.95, 0.98 or more (see, e.g., Sharifova, S., et. al., (2013), Journal of Hort. Research, 21(1):83-89; Ince et al., (2010), Biochem. Genet. 48:83-95; Parvathaneni et al., (2011), J. Crop Sci. Biotech, 14 (1): 39˜43; Pisanu, et. al., (2004), Acta Hort. 660, 83-89). The disclosure also provides a plant and a variety obtained or selected by applying these methods on NUN 09220 TOF. Such a plant may be produced by crossing and/or selfing, or alternatively, a plant may simply be identified and selected amongst plants of said variety, or progeny of said variety, e.g. by identifying a variant within NUN 09220 TOF or within progeny of said variety (e.g., produced by selfing) which variant differs from the variety described herein in one, two or three of the morphological and/or physiological characteristics (e.g., in one, two or three distinguishing characteristics), e.g. those listed in Table 1 and/or 2 and/or 3. In one aspect, the disclosure provides a tomato plant having a Jaccard's Similarity index with NUN 09220 TOF of at least 0.8, e.g. at least 0.85, 0.9, 0.95, 0.98 or even at least 0.99.

In some aspects, the disclosure provides a tomato plant comprising genomic DNA having at least 95%, 96%, 97%, 98% or 99% sequence identity compared to the genomic DNA sequence of a plant of NUN 09220 TOF as deposited under Accession Number NCIMB 43617. In some aspects, the tomato plant further comprises all or all but 1, 2, or 3 of the morphological and physiological characteristics of NUN 09220 TOF (e.g., as listed in Table 1 and/or 2 and/or 3). In other aspects, the tomato plant is a hybrid or other derived from a seed or plant of NUN 09220 TOF. In other aspects, the tomato plant comprises the distinguishing characteristics of NUN 09220 TOF.

For the purpose of this disclosure, the “sequence identity” of nucleotide sequences, expressed as a percentage, refers to the number of positions in the two optimally aligned sequences which have identical residues (×100) divided by the number of positions compared. A gap, i.e., a position in the pairwise alignment where a residue is present in one sequence but not in the other, is regarded as a position with non-identical residues. A pairwise global sequence alignment of two nucleotide sequences is found by aligning the two sequences over the entire length according to the Needleman and Wunsch global alignment algorithm described in Needleman and Wunsch, 1970, J. Mol. Biol. 48(3):443-53. A full implementation of the Needleman-Wunsch global alignment algorithm is found in the needle program in The European Molecular Biology Open Software Suite (see, e.g., EMBOSS, Rice et al., Trends in Genetics June 2000, vol. 16, No. 6. pp. 276-277).

The description also provides methods for determining the identity of parental lines of plants described herein, in particular, the identity of the female line. US2015/0126380, which is hereby incorporated by reference, relates to a non-destructive method for analyzing maternal DNA of a seed. In this method, the DNA is dislodged from the seed coat surface and can be used to collect information on the genome of the maternal parent of the seed. This method for analyzing maternal DNA of a seed comprises contacting a seed with a fluid to dislodge DNA from the seed coat surface, and analyzing the DNA thus dislodged from the seed coat surface using methods known in the art. The skilled person is thus able to determine whether a seed has grown on a plant of a plant of NUN 09220 TOF or is a progeny of said variety, because the seed coat of the seed is a maternal tissue genetically identical to said variety. In one aspect, the present disclosure relates to a seed coat comprising maternal tissue of NUN 09220 TOF. In another aspect, the disclosure relates to a tomato seed comprising a maternal tissue of NUN 09220 TOF. In another particular aspect, the disclosure provides for a method of identifying the female parental line of NUN 09220 TOF by analyzing the seed coat of a seed of that variety. In another aspect, the disclosure provides for a method of determining whether a seed is grown on NUN 09220 TOF by analyzing the seed coat or another maternal tissue of said seed.

By crossing and/or selfing (one or more), single traits may be introduced into NUN 09220 TOF (e.g., using backcrossing breeding schemes), while retaining the remaining morphological and physiological characteristics of said variety and/or while retaining one or more or all distinguishing characteristics. A single trait converted plant may thereby be produced. For example, disease resistance genes may be introduced, genes responsible for one or more quality traits, yield, etc. Both single genes (e.g., dominant or recessive) and one or more QTLs (quantitative trait loci) may be transferred into NUN 09220 TOF by breeding with said variety.

Alternatively, a single trait converted plant or single locus converted plant of NUN 09220 TOF may be produced by (i) genetically transforming or mutating cells of NUN 09220 TOF; (ii) growing the cells into a plant; and (iii) optionally selecting a plant that contains the desired single locus conversion. The skilled person is familiar with various techniques for genetically transforming a single locus in a plant cell, or mutating said cells.

Any pest or disease resistance genes may be introduced into a plant NUN 09220 TOF, progeny of said variety or into a plant comprising all but 1, 2, or 3 or more of the morphological and physiological characteristics of NUN 09220 TOF (e.g., as listed in Table 1 and/or 2 and/or 3).

In one aspect, a plant of NUN 09220 TOF may also be mutated (by e.g., irradiation, chemical mutagenesis, heat treatment, etc.) and mutated seeds or plants may be selected in order to change one or more characteristics of said variety. Methods such as TILLING may be applied to tomato populations in order to identify mutants. Similarly, NUN 09220 TOF may be transformed and regenerated, whereby one or more chimeric genes are introduced into the variety or into a plant comprising all but 1, 2, 3, or more of the morphological and physiological characteristics (e.g., as listed in Table 1 and/or 2 and/or 3). Transformation can be carried out using standard methods, such as Agrobacterium tumefaciens mediated transformation or biolistics, followed by selection of the transformed cells and regeneration into plants. A desired trait (e.g., gene(s) conferring pest or disease resistance, herbicide, fungicide or insecticide tolerance, etc.) can be introduced into NUN 09220 TOF, or progeny of said variety, by transforming said variety or progeny of said variety with a transgene that confers the desired trait, wherein the transformed plant retains all or all but one, two or three of the phenotypic and/or morphological and/or physiological characteristics of NUN 09220 TOF or the progeny of said variety and contains the desired trait.

Haploid and doubled haploid (DH) plants can, for example, be produced by cell or tissue culture and chromosome doubling agents and regeneration into a whole plant. For example, DH production chromosome doubling may be induced using known methods, such as colchicine treatment or the like. In one aspect, the method comprises inducing a cell or tissue culture with a chromosome doubling agent and regenerating the cells or tissues into a whole plant.

In another aspect, the disclosure comprises a method for making doubled haploid cells from haploid cells of NUN 09220 TOF comprising doubling cells of NUN 09220 TOF with a doubling agent, such as colchicine treatment (see, e.g., Nikolova V, Niemirowicz-Szczytt K (1996) Acta Soc Bot Pol 65:311-317).

In another aspect, the disclosure provides for haploid plants and/or doubled haploid plants derived from NUN 09220 TOF that, when combined, make a set of parents of NUN 09220 TOF. The haploid plant and/or the doubled haploid plant of NUN 09220 TOF can be used in a method for generating parental lines of NUN 09220 TOF.

Using methods known in the art such as “reverse synthesis of breeding lines” or “reverse breeding”, it is possible to produce parental lines for a hybrid plant such as NUN 09220 TOF. A skilled person can take any individual heterozygous plant (called a “phenotypically superior plant” in Example 2 of US2015/0245570 hereby incorporated by reference in its entirety; NUN 09220 TOF is such plant) and generate a combination of parental lines (reverse breeding parental lines) that, when crossed, produce the variety NUN 09220 TOF. It is not necessary that the reverse breeding parental lines are identical to the original parental lines. Such new breeding methods are based on the segregation of individual alleles in the spores produced by a desired plant and/or in the progeny derived from the self-pollination of that desired plant, and on the subsequent identification of suitable progeny plants in one generation, or in a limited number of inbred cycles. Such a method is known from US2015/0245570 or from Wijnker et al., Nature Protocols Volume: 9, Pages: 761-772 (2014) DOI: doi:10.1038/nprot.2014.049.

EXAMPLES

Development of NUN 09220 TOF

The hybrid NUN 09220 TOF was developed from a male and female proprietary inbred line of Nunhems. The female and male parents were crossed to produce hybrid (F1) seeds of NUN 09220 TOF. The seeds of NUN 09220 TOF can be grown to produce hybrid plants and parts thereof (e.g., tomato fruit). The hybrid NUN 09220 TOF can be propagated by seeds or vegetative.

The hybrid variety is uniform and genetically stable. This has been established through evaluation of horticultural characteristics. Several hybrid seed production events resulted in no observable deviation in genetic stability. Coupled with the confirmation of genetic stability of the female and male parents the Applicant has concluded that NUN 09220 TOF is uniform and stable.
